The index setting unit sets an index and a weighting factor. The index represents information of a reference image. The index reconfiguring unit predicts a reference value of the weighting factor. The reference value indicates a factor to be set if a difference of pixel value between a reference image and a target image to be encoded is less than or equal to a specific value. The entropy encoding unit encodes a difference value between the weighting factor and the reference value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Encoding device, decoding device, encoding method, and decoding method for efficient coding","description":"According to an embodiment, an encoding device includes an index setting unit, an index reconfiguring unit, and an entropy encoding unit.
